For 360|AnDev this year, we built a web front-end to help manage the speaker submission process and scheduling details. The apps was built using AngularJS and connected into the existing Firebase database we initially starting using last year. Similar to my initial Firebase reactions, AngularJS made things much easier than I had expected.

A deeper look into the internal structure and mechanics of ConstraintLayout. We will examine the measure and layout passes, in addition to how constraints are resolved. Let’s see if we can strip away some of the magic of this new container to better understand how the whole process works.

An examination of the basics of the ConstraintLayout container and what features are available to developers. ConstraintLayout is sold as a flexible container that will drastically simply flattening view hierarchies and reduce nesting. We will look at the XML attributes that define constraints, and the view measurement semantics used.

As one of the co-organizers of 360|AnDev, I took it upon myself to build the conference Android app. To avoid the headaches of setting up back-end infrastructure, I turned to Firebase to provide the services we needed to get the job done.

I was recently tasked with constructing an Android API that followed the design tenets of Google Play Services in form and function. Many who have discovered this API for the first time after using the Android framework for a while often have with a similar feeling — it feels like an overly complex surface area.

Even with all the current and upcoming changes in the Android compiler toolchains and build systems used for both applications and the platform, one common issue continues to come up amongst Android platform developer community: What is the best way to develop platform applications given the current state of the tools?

After you’ve fed some data into the Proximity Beacon API, how do you retrieve that information client-side when the mobile device observes your beacons out in the wild? In this article, we’ll discuss how the Nearby Messages API provides the missing link to make this easy.
